If you want to use them, submit a request to the CAD or either of the DCADs. (Note: the airworthiness team is very reluctant to have inflight recharging of lithium batteries).
There will be a technical review done and then a trial period. If all goes well, an addition to the MTAR is possible. The Fusion batteries need a dumb charger. A battery with inbuilt protection circuits is highly likely to have a conflict with a smart charger unless the programming is identical and wont recharge properly.

The internal circuitry is designed to make the battery "look" like a standard lead acid or gel cell type and the EarthX brand is used in Experimental homebuilts connected to the charging system instead of a lead acid or gel cell. That brand also can be used for engine starting. They are available in Australia. There was a good article in Kitplanes a while ago on the manufacture and testing of those. As the battery "looks" like a standard lead acid no mods to the aircraft charging circuit are necessary and any good lead acid battery charger should work. If you try to use an intelligent LiFePO4 charger you may get a conflict between the battery internal protection and the intelligent charger. See that. It would be nice to know what exactly the approval process for the Fusion brand involved. Mike .
